NYU scientists advance toward nanorobots
A new device allows for localized movement in molecular scale DNA constructs, advancing the study of nano-scale robotics.

New technology detects lying, paves way for increased security
A Mayo Clinic-led study that appears in the Jan. 3, 2002 edition of Nature found that a new high-definition technology that involves measurement of the heat patterns created by the face accurately detected lying in more than 80 percent of cases studied.

Monitoring epithelial plasticity, one cell at a time
The kidneys maintain plasma volume and composition by adapting to shifts in the concentration of ions and other solutes.

Study finds there's a critical time for learning all languages, including sign language
Neuroscientists examining the brain activity of people who learned to speak American Sign Language (ASL) at different times in their lives have found the first evidence that there is a critical period for acquiring a non-verbal language, just as there is for spoken languages.

New generation antipsychotic drug cuts relapse rate in patients with schizophrenia
A second-generation antipsychotic drug lowers the risk of relapse in patients with schizophrenia by nearly half, according to a team of researchers, led by psychiatrists at Washington University School of Medicine in St.

CNS cell death in bacterial meningitis
Bacterial infection of the CNS is hazardous not only because of its often-lethal acute effects, but also because it leads to the death of irreplaceable neurons and glia.

Study finds that steroids soothe sore throat pain
A Mayo Clinic study published in the January edition of Laryngoscope has found that a single 10 mg dose of the steroid dexamethasone provides safe, effective and inexpensive treatment for bacterial or viral pharyngitis (sore throat).

Secret code machine
A Harvard professor of computer science is building a secret code machine - an Enigma for the 21st century.

Study suggests way to short-circuit microbe communication
For cell-phone toting humans, the ability to communicate depends on a vast array of technology that includes things like amplifiers and repeaters to speed our words through the ether and ensure their intact arrival at a distant location.

UPM archaeologist asserts that enigmatic ivory statuette may be part of the throne of the famed King Midas
It isn't made of gold, but a well-known and much-discussed ivory statuette of a lion-tamer, found in 1939 at Delphi, may very well be part of the throne given to the god Apollo by the famous King Midas of Phrygia.

Rutgers cell biologist sees new HIV treatment potential in protein discovery
Rutgers cell biologist Bonnie L. Firestein is charting a new course in the search for an effective AIDS treatment.

Inherent speed limit governs how quickly life bounces back after extinction, UC Berkeley research shows
Species can disappear catastrophically, as in an asteroid impact, or slowly, over tens of millions of years.

Nature's own medicine for vision loss: Inhibitor of angiogenesis found by biologists at The Scripps Research Institute
A potentially potent inhibitor of angiogenesis, the process whereby new blood vessels are formed from existing ones, can be found in one of the very molecules involved in the same process.

Baby talk
Baby talk may sound silly, but it makes sense to babies and may help children learn how to speak.

The anti-inflammatory effect of apoptotic bodies
The ubiquitous process of apoptotic cell death escaped the notice of cell biologists for decades, largely because cells that die by this mechanism are efficiently removed by phagocytosis in a process that provokes no local inflammation.

White sharks migrate thousands of miles across the sea, new study finds
A new study is shattering old beliefs about the great white shark  - one of the largest, most awe-inspiring predators in the sea.
